(1)
AIN12 is not selectable in ADC scan mode or with analog watchdog.
(2)
In 44-pin package, AIN9 cannot be used by ADC scan mode.
(3)
In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer and protection diode to VDD are not implemented).
Alternate function remapping
5.1.1
As shown in the rightmost column of the pin description table, some alternate functions can
be remapped at different I/O ports by programming one of eight AFR (alternate function
remap) option bits. When the remapping option is active, the default alternate function is no
longer available.
To use an alternate function, the corresponding peripheral must be enabled in the peripheral
registers.
Alternate function remapping does not effect GPIO capabilities of the I/O ports (see the GPIO
section of the family reference manual, RM0016).
